> **📅 Research snapshot as of 2026-04-21.** Provider pricing, free-tier availability, and model capabilities drift every quarter. The router reads `data/routing-table.json` and `data/model-registry.json` at runtime — treat those as source of truth. If this document disagrees with the registry, the registry wins.

# Category 06 — Stable Diffusion Flux

Open-weight stacks — SD 1.5 / SDXL / SD3 / Flux.1 / Flux.2 / Kontext: the two prompting contracts (CLIP tag-salad vs T5/VLM prose), Flux's negative-prompt rejection, ControlNet / IP-Adapter / LoRA primitives.
